Draw Circle

Circles can be created interactively with the cursor and Quick Keys or by entering the exact coordinates and diameter / radius with typed input.

Watch this video to see this in action:

Interactive

Cursor

The default mode and the procedure for drawing circle is:
Click and drag the Left mouse to indicate the center point followed by releasing the button at the required radius / diameter (depends on what is set on the form).

Note

Holding Alt and dragging creates a circle from the middlepoint.

As the cursor is dragged across the screen the radius is dynamically updated. The increments will depend upon your snap radius and the job size.

Quick Keys

The radius or diameter can be specified while dragging out a circle:

Type the value while dragging followed, by D if it's a diameter, or R if it's a radius:

Example:

1 2 R Gives a radius of 12

Exact Size

Circles can also be drawn by entering the required XY origin, selecting either Radius or Diameter and entering the required size on the form.

Click Create to update the circle.

Edit

Open the Draw Circle form and select the circle to modify.

The selected circle is displayed as a dotted magenta line. Edit the Center Point and Radius or Diameter

Click to update the circle

To modify another circle without closing the form hold a Shift key down and select the next circle.

Close the form

To finish drawing with the tool, you can :

Click Close on the form

  • Press the key Esc
  • Click the Right mouse button in the 2D View

Usable In Both Views

This tool can be used in both the 2D and 3D View.

2D View offers a more direct way to view your vectors while the 3D view offers more flexibility to work with Vectors in 3D Designs and to make use of the Edit Boxes.

When in the 2D view, a number of the forms tools will be driven by options in the form only.

  • Middle - Move the vectors (Hold Alt and move the selected objects in one axis)
  • Middle - Click a second time to switch to Rotational center. Click and drag the Rotational Anchor to reposition the Rotational Center of the current selection.
  • Corner (White) - Scale the vectors proportionally (Hold Alt for scaling non-proportionally, Shift to scale around the centre)
  • Edges (White) - Scale the vector in one axis (Hold Shift for scaling proportionally)
  • Corner (Black) - Rotate the vectors (Hold Alt to Rotate in 15° increments) about the Rotation Center.

In the 3D view, there is an expanded number of handles to directly edit the vector within the view, without needing to use the creation form on the left.

In the 3D View, the Handles are:

  • Middle - Move the vectors (Hold Alt to Move the selected objects in one axis)
  • Middle - Click a second time to switch to Rotational center. Click and drag the Rotational Anchor to reposition the Rotational Center of the current selection.
  • Corner (White) - Scale the vectors proportionally (HoldAlt for scaling non-proportionally, orShift to scale around the centre)
  • Edges (Black) - Scale the vector in one axis (Hold Shift for scaling proportionally)
  • Rotation Arrow (Top Black) - Rotate the vectors (Hold Alt to rotate in 15° increments)
  • White circles are properties unique to this tool to allow direct mouse editing of values in the tool form from within the view.

When you select a Transform Handle, it will activate the appropriate Edit Box for that Handle.

If you need an exact value for a field while dragging it, release the mouse button and type in the desired value, followed by Enter to accept the new value.
